Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 1～shown in Figure 6, the audio amplifier take-up mechanism that the utility model embodiment provides, in audio amplifier 1, be provided with the unidirectional take-up mechanism 2 of a gear, the unidirectional take-up mechanism 2 of described gear comprises loam cake 21 and lower cover 22, rotate in the cavity that described loam cake 21 and lower cover 22 form and be provided with coaxial band tooth resilient arm 23 and band tooth transmission rotating disk 24, be wound with connecting line 25 on the described band tooth transmission rotating disk 24, the elastic arm 231 of described band tooth resilient arm 23 engages with the step tooth 241 of described band tooth transmission rotating disk 24 bottoms, rotate on the base 11 of described audio amplifier 1 and be provided with gear turntable 26, described gear turntable 26 stretches out outside the described base 11, the gear 261 of described gear turntable 26 and 232 engagements of the gear of described band tooth resilient arm 23.
As Fig. 2 and shown in Figure 5, particularly, be installed with first installation shaft 221 in the described lower cover 22, described band tooth resilient arm 23 and band tooth transmission rotating disk 24 rotate to be located on described first installation shaft 221, after assembling was finished, the elastic arm 231 of band tooth resilient arm 23 just was stuck on the step tooth 241 of band tooth transmission rotating disk 24 bottoms.Offer the winding slot 242 of circumferential setting on the described band tooth transmission rotating disk 24, described connecting line 25 rich being located in the described winding slot 242.Described step tooth 241 is for to have the boss on inclined plane, and presses the bottom of circumferencial direction spaced set in described band tooth transmission rotating disk 24.When band tooth resilient arm 23 is just changeing, band tooth resilient arm 23 imposes on the thrust of step tooth 241 along band tooth transmission rotating disk 24 circumferencial directions by elastic arm 231, also just change thereby promote band tooth transmission rotating disk 24, band tooth transmission rotating disk 24 is wound on connecting line 25 in the winding slot 242 when just changeing thereupon; When 23 counter-rotatings of band tooth resilient arm, the elastic arm 231 of band tooth resilient arm 5 skids off along the inclined plane of the step tooth 241 of band tooth transmission rotating disk 24, make band tooth transmission rotating disk 24 and band tooth resilient arm 23 break away from interlock, band tooth transmission rotating disk 24 is in actionless state, like this, being wound on connecting lines 25 in the winding slot 242 of band tooth transmission rotating disk 24 can not skid off take-up mechanism because of the counter-rotating of band tooth resilient arm 23 and cause connecting line 25 and tie a knot in audio amplifier 1 or block line.Compare with the existing automatic unidirectional take-up mechanism of forming by metal scrollwork reed and rolling steel ball of scroll-type, the utility model adopts the unidirectional take-up mechanism 2 of gear to realize the take-up purpose, the gear mechanism reliable transmission, long service life has been avoided weakening the phenomenon that causes fault because of the resilience dynamics of existing metal scrollwork reed.
As shown in Figure 6, particularly, be installed with second installation shaft 111 on the base 11 of described audio amplifier 1, described gear turntable 26 rotates to be located on described second installation shaft 111, after the installation, gear 261 on the gear turntable 26 meshes with the gear 232 of band tooth resilient arm 23, the gear 261 on the handsetting gear rotating disk 26, and band tooth resilient arm 23 also can rotate thereupon.
As Fig. 1～shown in Figure 6, the audio amplifier take-up mechanism that the utility model provides in use, be pulled outwardly the line 25 that is dynamically connected, connecting line 25 can be pulled out smoothly, thereby connecting line 25 is connected on other electric equipments, as connecting line 25 being connected to the voice output interface of audio-frequence player device, like this, audio amplifier 1 just can have been play outer sound; When needs are covered up connecting line 25, manual unidirectional handsetting gear rotating disk 26, gear turntable 26 is just being changeed, gear turntable 26 drives the band tooth resilient arm 23 that is engaged with also and then just to be changeed, the band tooth transmission rotating disk 24 that band tooth resilient arm 23 drives engaging with it also and then just changes, band tooth transmission rotating disk 24 when just changeing with connecting line 25 rollings in winding slot 242, thereby realize the purpose of the connecting line 25 of the unidirectional take-up mechanism 2 collection audio amplifiers 1 of gear.
When user's opposite direction handsetting gear rotating disk 26, the band tooth resilient arm 23 that gear turntable 26 drives are engaged with is backward rotation also, the elastic arm 231 of band tooth resilient arm 23 skids off by rank in the other direction along the inclined plane of the step tooth 241 of band tooth transmission rotating disk 24, make band tooth transmission rotating disk 24 and band tooth resilient arm 23 break away from interlock in the other direction, thereby can effectively avoid connecting line 25 to cause connecting line 25 and in audio amplifier 1, tie a knot or block line and cause fault because of gear turntable 26 counter-rotatings skid off take-up mechanism.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
